Phil McGraw, 64, famously known as Dr. Phil, recently joked about the alleged gender transition of Bruce Jenner, 65.

During his appearance on the "Jimmy Kimmel Live!" late night show on April 22, Wednesday, Dr. Phil was asked if he was disappointed that he did not get the exclusive interview with the former Olympian, who has a two-hour special with Diane Sawyer set to be aired on April 24, Friday.

Dr. Phil told Jimmy Kimmel, "It would be boring to talk to me about that. First off, I would say, 'Look if it's what you want to do, do it. I mean, what the hell does it matter what anybody else thinks.'"

The famed doctor received a round of applause from the "Jimmy Kimmel Live!" audience until he joked, "That'd be the first 30 seconds and then I guess we'd spend the next hour and 59 minutes saying 'You're almost 80, what's the point?' This is a theoretical exercise, right?"

After suggesting that Jenner may be past his prime, Kimmel defended the 1976 Summer Olympics decathlon gold medallist saying he would not put anything past him.

"I mean, he may be a champion in the bed as well," Kimmel said of Jenner.

On the same episode, Dr. Phil met Manny Pacquiao, 36. He asked the Filipino boxing champ why he has to fight against Floyd Mayweather Jr.

When Pacquiao joked it was just for the money, Dr. Phil gave him a piece of advice that has to be bleeped.

In a recent interview with The Telegraph, Pacquiao said God is with him so he has peace of mind.

Meanwhile, days before the airing of his interview with Sawyer, Jenner was spotted wearing a black-and-white striped dress outside his house in Malibu, according to New York Daily News.
